In die casting it could be necessary to repress during the solidification process. In such processes they like to use so-called “squeeze pins”.

The cavity is often over pressurized by using a round pin with a very high force.

The hydraulic cylinder can be dimensioned with this calculation tool. The required parameters are the needed: intensification pressure, the hydraulic system pressure, and the pin diameter.

With these parameters the calculation tool will show the calculated piston diameter and the next possible piston diameter. In this calculation a pulling direction or double rod cylinder will not be considered, only that the cylinder will use the full piston surface.



For the basis of calculation use the following formula:


Essential Formula Parameters:

  • d1 = Diameter Squeeze Pin
  • D = Piston diameter
  • p1 = Needed intensification pressure
  • p2 = Hydraulic system pressure
